pylint-2.8.1

• Add numversion back (temporarily) in __pkginfo__ because it broke Pylama and revert the unnecessary
  pylint.version breaking change.

  Closes #4399

pylint-2.8.0

• New refactoring message consider-using-with. This message is emitted if resource-allocating functions or methods of the
  standard library (like open() or threading.Lock.acquire()) that can be used as a context manager are called without
  a with block.

  Closes #3413

• Resolve false positives on unused variables in decorator functions

  Closes #4252

• Add new extension ConfusingConsecutiveElifChecker. This optional checker emits a refactoring message (R5601 confusing-consecutive-elif)
  if if/elif statements with different indentation levels follow directly one after the other.

• New option --output=<file> to output result to a file rather than printing to stdout.

  Closes #1070

• Use a prescriptive message for unidiomatic-typecheck

  Closes #3891

  typing.Final

  not packaged anymore - reducing the size of the package by 75%.

• Debian packaging is now (officially) done in https://salsa.debian.org/python-team/packages/pylint.

• The 'doc' extra-require has been removed.

• __pkginfo__ now only contain __version__ (also accessible with pylint.__version__), other meta-information are still
  accessible with import importlib;metadata.metadata('pylint').

  Closes #3406

• Don't auto-enable postponed evaluation of type annotations with Python 3.10

• Update astroid to 2.5.4

• Add new extension TypingChecker. This optional checker can detect the use of deprecated typing aliases
  and can suggest the use of the alternative union syntax where possible.
  (For example, 'typing.Dict' can be replaced by 'dict', and 'typing.Unions' by '|', etc.)
  Make sure to check the config options if you plan on using it!

• Reactivates old counts in report mode.

  Closes #3819

• During detection of inconsistent-return-statements consider that assert False is a return node.

  Closes #4019

• Run will not fail if score exactly equals config.fail_under.

• Functions that never returns may declare NoReturn as type hints, so that
  inconsistent-return-statements is not emitted.

  Closes #4122, #4188

• Improved protected access checks to allow access inside class methods

  Closes #1159

• Fix issue with PEP 585 syntax and the use of collections.abc.Set

  Closes #4265

• Fix issue with annotated class constants

  • Closes #4264

pylint-2.7.3

• Introduce logic for checking deprecated attributes in DeprecationMixin.

• Reduce usage of blacklist/whitelist terminology. Notably, extension-pkg-allow-list is an

pylint-2.6.2

• Astroid version has been set as < 2.5

  Close #4093

pylint-2.6.0

• Fix various scope-related bugs in undefined-variable checker

  Close #1082, #3434, #3461

• bad-continuation and bad-whitespace have been removed, black or another formatter can help you with this better than Pylint

  Close #246, #289, #638, #747, #1148, #1179, #1943, #2041, #2301, #2304, #2944, #3565

  Close #3564

• Add raise-missing-from check for exceptions that should have a cause.

• Support both isort 4 and isort 5. If you have pinned isort 4 in your projet requirements, nothing changes. If you use isort 5, though, note that the known-standard-library option is not interpreted the same in isort 4 and isort 5 (see the migration guide in isort documentation for further details). For compatibility's sake for most pylint users, the known-standard-library option in pylint now maps to extra-standard-library in isort 5. If you really want what known-standard-library now means in isort 5, you must disable the wrong-import-order check in pylint and run isort manually with a proper isort configuration file.

  Close #3722
